JOE MILLER, OF BUFFALO, NEW YORK.

' -VALVE-GRINDER.

Application filed December 30, 1920.

T 0 all 107107 it may concern Be it known that T, Jon MILLER, of the United States, residing at Buffalo, in the county of Erie and State of New 1 ork, have invented certain new and useful Improvements in Valve-Grinders, of which the following is a Specification.

This invention relates to valve grinders, the primary object of which is to provide a simple type of implement which may be conveniently used by anyone on any standard type of valves.

Another object of the invention is to provide a valve oscillator which may be held and actuated by one hand, thereby especially adapting the device for use in finishing the valves.

The above and other objects of this inven tion will be in part described and in part understood from the following description of the present preferred embodiment of the invention taken in connection with the accompanying drawings, wherein:

Figure 1, is a perspective view of a grinder constructed in accordance with this invention, and

Fig. 2, is a fragmentary sectional view of the device showing to advantage the manner of connection between the oscillating rod and actuating wheel.

In the drawings, a rod 3 is provided which is preferably of a cylindrical configuration and made solid throughout. One end thereof is bifurcated and receives a valve engaging member 4 between the branches of the bifurcation. This member is detachably held by a screw 5 orother desired means permitting expeditious removal of said member. The valve head engaging member 4 may be of the usual or any desired configuration for use with different types of valves.

The opposite end of the rod 3 is equipped with a handle 6, which is swiveled on the rod to permit movement of the latter independently of the handle. The handle in this instance is shown to be of a circular configuration so as to form a convenient support for the palm of the hand through the medium of which the member at is held in the valve head.

The rod 3 is provided with screw threads 7 adjacent its lower end which are adapted for the reception of a rod actuating wheel 8. This wheel is shown in the present in a citizen Specification of Letters Patent.

Serial No. 434,007.

stance to be of a disk formation and is preferably circular in configuration. It may be adjusted on said rod to the extent of the screw threads 7, permitting use of the wheel at any desired height. The wheel is held in a predetermined position by means of jam nuts 9, which are arranged above and below said wheel and engaged therewith as shown to advantage in Fig. 2. The actuating wheel is'of a relatively large size so as to be conveniently grasped by the hand of the operator for oscillating the rod 3, thereby imparting a corresponding movement to the valve with results well known in the art.

A secondary actuating wheel or disk 10 is forced on the rod 8 and is arranged in close proximity to the handle 6 so that the operators lingers which overhang the periphery of the handle 6, when engaged with the latter, may contact with said wheel, permitting movement to be imparted thereto for correspondingly moving or rotating the rod 3 in order to finish work on the valve.

It is to be understood that in use of this devicethe hand of the operator is engaged with the handle 6 so as to hold the member t in engagement with the valve head. Oscil latory movement is then imparted to the wheel 8, causing the latter to oscillate the rod 3. After the rough work on the valve has been completed, the face of the valve may be finished by using the disk 10 in a manner above described.

Various changes may be made in this device in the form and arrangement of parts within the scope f the appended claims.

What is claimed is:

1. A valve grinder including a rod equipped with a valve engaging member on one end and a handle on the opposite end, primary rod oscillating means mounted upon the rod adjacent said valve engaging member, and secondary rod oscillating means mounted upon the rod adjacent the handle.

2. A valve grinder including a rod equipped with a valve engaging member on one end and a handle on the opposite end, a rod oscillating wheel adjustably mounted on said rod adjacent the valve engaging member, and a rod oscillating wheel mounted on said rod adjacent said handle.

3. A valve grinder including an oscillating rod equipped with valve engaging means on one end and a handle on the opposite end,

means mounted upon said rod to oscillate In testimony whereof I aifix my signature the same, and secondary means mounted on in presence of two witnesses. the rod to oscillate the same, said secondary JOE MILLER means being arranged in proximity to said 5 handle to be operated by the fingers of the Witnesses:

hand of the operator which engages said D. M. KENNEY, handle. W. S. BARKER.
